WINDOW-SASII HOLDER.

To all who/m t may concern.'

Be it known that I, CHRISTIAN W. Cook, citizen of the United States,residing at Provo, in the county of Utah and State of Utah, haveinvented certain new and useful Improvements in VVindow-Sash Holders, ofwhich the following is a specification.

This invention may be applied to windows in which a link is used to holdthe window open, and is especially applicable to windows in which thesash is hinged at one side, and its novelty resides partly in the linkitself, and also in the guide which controls and limits the movement ofthe link.

The accompanying drawings illustrate the device, in which- Figure 1, isa front elevation of a part of a window frame, as viewed from theoutside, and having my invention connected therewith. Fig. 2 is a planview of a cross section on line of Fig. 1, with the window open. Fig. 3is a plan view of the under side of the link with the guide thereon, anddetached from the window, and Fig. 4 is a cross section on line i/-y ofFig. 3.

Like figures of reference denote corresponding parts, in the severalviews.

Referring to the drawing, the numeral 1, designates a window frame and 2the window sill.

3 denotes the window sash and 5 the lower sash bar. The sash is hingedto the frame at one side, the lower hinge appearing at 4.

6 is a plate or link having a perforation 7 at one end, and recesses 8,8, along one edge. The link 6 is rotatably secured to the window sill 2,by a screw 10, which passes through the perforation 7. The plate 6 isadapted to move in a guide 12, which is loosely fastened to the underside of the lower sash bar by a pin or screw 14. The guide 12 is formedfrom a plate having its ends bent over toward each other, and spacedapart sufficiently to permit the link 6 to move readily in it. The outerend of the Specification of Letters Patent. Application led December 9,1910, Serial No. 596,485. Renewed February 1, 1913.

link is upbent to form a flange 9, to prevent the link from slipping outof the guide. The head of the screw 14, is adapted to engage therecesses 8 in the link by which means the window is held at any desiredpoint.

A recess 15, is formed at one side of the guide to allow the guide tomove in closely when shutting the window without interference from thescrew 10.

It should be noticed that the hole 16, in the under side of the guide12, is large enough to permit the head 13, of the screw 14, to passentirely through it and to rest loosely against the upper side of theguide. The head 13 ofthe screw 14, has, preferably, a verticalmeasurement, equal to, or greater' than, the thickness of the link 6.

I do not limit the application of the device to the bottom of a window,as it may be applied to the sides or the top of the sash.

What I claim and desire to secure is,-

The combination with a window casing having a hinged sash of a linkprovided with lateral recesses and adapted for pivotal attachment at oneend to the window casing, a guide on said link composed of a plate withits ends folded over toward each other and its upper and lower portionsspaced apart to movably admit said link, said 'guide having a relativelylarge perforation through its under side and a smaller perforationthrough its upper side, a screw having a cylindrical head adapted topass through said large perforation in the under side of said guide andto be engaged by said lateral recesses in said link, said screw beingadapted to movably secure said guide to the lower edge of said sash, andan uptluned terminal flange on said link to retain said guide thereon.

In testimony whereof I ailix my signature, in presence of two witnesses.

CHRISTIAN W. COOK.
